We're dividing 2604 by 99 
The aim is to understand the frequency of 99 in 2604.

On to step 1:
99 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 99

Step 2:
When dividing 26 by 99, we get 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 99

Moving on to step 3:
99 goes into 260 2 times with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 198 from 260 to get 62.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 99

On to step 4:
If we divide 624 by 99, we get 6 and a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 594 away from 624, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 5:
The number 99 fits into 300 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 26.3
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
If we divide 30 by 99, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 26.3
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
When dividing 300 by 99, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 26.303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
99 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 26.303
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 26.30303
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
99 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 26.30303
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
When dividing 300 by 99, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 26.3030303
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
30 divided by 99 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 26.3030303
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 26.3030303 with a balance of 3e-08.
